Use the following ToBitmapSource function to convert an IImage (which could be any of Image<TColor, TDepth> class) to a WPF BitmapSource.

<source lang="csharp"> ... using Emgu.CV; using System.Runtime.InteropServices; ...

       /// <summary>
       /// Delete a GDI object
       /// </summary>
       /// <param name="o">The poniter to the GDI object to be deleted</param>
       /// <returns></returns>
       [DllImport("gdi32")]
       private static extern int DeleteObject(IntPtr o);

       /// <summary>
       /// Convert an IImage to a WPF BitmapSource. The result can be used in the Set Property of Image.Source
       /// </summary>
       /// <param name="image">The Emgu CV Image</param>
       /// <returns>The equivalent BitmapSource</returns>
       public static BitmapSource ToBitmapSource(IImage image)
       {
           using (System.Drawing.Bitmap source = image.Bitmap)
           {
               IntPtr ptr = source.GetHbitmap(); //obtain the Hbitmap
              
               BitmapSource bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
                   ptr,
                   IntPtr.Zero,
                   Int32Rect.Empty,
                   System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());

               DeleteObject(ptr); //release the HBitmap
               return bs;
           }
       }

</source>
